Our EquipmentTinsel & PVC Pipe

GET STARTED!

I will hand out the supplies you need in class. Follow the directions under "What to do." Watch the video below to see how the levitating orb is possible!

Results

What happened & Why?

Since the pipe is negative and the tinsel orb is now negative, they repel away from each other and the orb levitates! The orb will also take on more of a “ball” appearance when charged since all the tinsel strands are repelling away from each otherPS.7.4.2

Arrange 6 strands of mylar together and tie them together in a knot at one end.Tie them together again about 6 inches (15cm) from the first knot.Cut the loose mylar strands off just past each knot.Charge the PVC pipe by rubbing it back and forth through your hair for 10 seconds.Hold the mylar orb (by the knot) above the charged pipe and let it drop and touch the pipe.

Similar static charges repel away from each other.When you rub the pipe in your hair you give the pipe a negative static charge. The orb is attracted to the pipe at first because the orb has a positive charge. As soon as the orb touches the pipe, it picks up a negative charge. Assignment! What is the conductor and what is the insulator? Explain why. Turn in by the end of class
